The above and other objects, features and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings.
(Outline of the Excrement Disposal Device 8)
An outline of the excrement disposal device 8 according to the present invention will now be described. This excrement disposal device 8 is made portable for use in outdoor activities, nursing-care services, military services or the like. This can be widely used as a handy-type excrement disposal device when toilet facilities are not available in the open air, be used for nursing-care services for a bed-ridden person on a bed, for use within a military vehicle at the battlefront and the like.
The excrement disposal device 8 has a base plate 9, a wing plate 10, a finger-inserting section 11, a disposal bag 12 and the like and is intended for an object such as excremental matter from a human body (a typical example is excrement, but urine and vomit are also acceptable).
The base plate 9, the wing plate 10 and the finger-inserting section 11 are made of a polypropylene sheet material, a resin sheet, a paper sheet or the like with bendability (flexural properties) of about 0.75 mm thickness which can be die-cut and then, slit up and bent, if necessary. The disposal bag 12 is made of a polyethylene film or other resin film which is flexible and is colored so that the content can not be seen.
Detailed description of the base plate 9, the wing plate 10, the finger-inserting section 11 and the disposal bag 12 are given hereunder.
(Base Plate 9)
The base plate 9 of the excrement disposal device 8 will be described with reference to
Each base plate 9 is longitudinally formed in a substantially long plate shape and can be bent upwards. In an example as shown in
The base plate 9 of about 140-150 mm long and 35 mm wide is longitudinally formed in a substantially long-plate shape to make the central section 14 high and to make the front end 13 and the rear end 13 (hereinafter referred to as “front and rear ends”) low. The base plate 9 can be bent upwards.
In the examples as shown in
The base plates 9 can be displaced between a longitudinally extended condition as shown in
The pivot pin 15 is normally a separate member from the base plates 9, but can be made integrally with the plates 9. In such a case, the pin is integrally set between the base plates 9 from the initial stage of molding.
Regardless of the examples as shown in
The inner side of each base plate 9 in the center is symmetrically provided with a cutaway section C opening inside. One continuous opening B is formed by the right and left cutaway sections C between two base plates 9.
The size of the opening C is made variable. That is, the size of the opening B is made large or small based on the symmetric displacement of both base plates 9 in the right and left direction (by) using the pin 15 serving as the pivot point of the front and rear ends 13 as a fulcrum. The cutaway section C as shown in the examples of
In
Each base plate 9 as shown in the examples of
Each base plate 9 as shown in the example is also provided with a central section 14 situated adjacent to the right and left areas D of the cutaway section C. The central section 14 is formed by two bent sections 18 bent upwards in a substantially convex shape. These bent sections 18 are formed by creasing the front and rear ends of the central section which are separated by about 10 mm. In this manner, as shown in
These bent sections 18 function to reduce the load on the fingertips A being basic to the displacement motion in the case where the base plates are caused to displace in the right and left direction while being bent, using the pin 15 which is a pivot point of the front and rear ends 13 and 13 pivotally attached as a fulcrum. In other words, the bent sections 18 function to stably displace both base plates 9.
Further, referring to an example as shown in
Namely, each base plate 9 as shown in the example of
The tongue piece 19 is respectively provided to put the guide projection 21 thereunder and guides to allow the wing plate 10 to slide on the base plate 9. Namely, the tongue piece 19 functions to stably slide the wing plate 10 so that the top section 22 of the sliding wing plate 10 does not warp upwards. In particular, the tongue piece 19 guides so as not to cause the top section 22 of the wing plate 10 to warp to produce a step when each wing plate 10 slides from the receded condition to the close condition to move back and forth.
(Wing Plate 10)
The wing plate 10 of this excrement disposal device 8 will be described hereunder with reference to
The front and rear wing plates 10 can be slightly bent upwards to symmetrically move back and forth and is provided to slide on both base plates 9.
The wing plate 10 is provided so that one end of the base end section 20 is pivotally secured to one of the right and left base plates 9, while another end of the base end section 20 is pivotally secured to another base plate 9. The size of the mouth section G is made variable by the displacement of the two base plates 9 in the horizontal directions, using the pivot pin 15 of the front and rear ends 13 and 13 as a fulcrum, and by the motion of longitudinally approaching or receding from the top sections 22 of both wing plates 10 in conjunction wit the displacement.
Such a wing plate 10 is further described in detail. Each wing plate 10 consists of the top section 22 and the forked base end section 20. The top section 22 is forked horizontally through a narrow central edge of, for example, about 5 mm width in the longitudinal direction, while the base end section 20 is provided as a continuation of the right and left forked section of the top section 22 to have a substantially fork shape.
The top section 22 is provided with displacement characteristics, folding characteristics, and bending characteristics in the center of the edge. The right and left base end sections 20 are pivotally secured to the corresponding right and left base plates 9, respectively, in a two-dimensional manner by pins 15′ of a vertical axis in the vicinity of the end. The distance between the right and left pins 15′ and 15′ is about 40 mm.
The pivot pin 15′ is normally made of a different material from the wing plate 10 and the base plate 9, but can be integrally formed with the base end section 20 of the wing plate 10 and the base plate 9. In this case, the pin 15′ is integrally set between the base end section 20 and the base plate 9 from the initial stage of molding.
The wing plates 10 are opposedly situated to be symmetrical in the longitudinal direction, facing the opening B from ahead and from behind and control the shape of the opening B in the longitudinal direction to form the mouth section G.
When the two base plates 9 are symmetrically displaced in the horizontal direction, the two wing plates 10 are also symmetrically displaced in the longitudinal direction through a pivot point by the pin 15′. With this displacement, the mouth section G formed based on the opening B is made variable by engaging the lateral dimensions with the vertical dimensions.
In other words, the two wing plates 10 can be displaced between the condition in which the edge of the top section 22 is substantially straight, as shown in
The displacement of such wing plates 10 results from the fact that the base plates 9 are displaced between the condition as shown in
In the case where the size of the opening B formed by the two base plates 9 is small (refer to
Each edge of the top sections 22 of the front and rear wing plates 10 is provided with a cushion piece (not shown) made of, for example, rubber. This cushion piece is caused to touch the anus area from below through the mouth periphery 23 of the disposal bag 12 to exhibit the cushion performance against the anus and the eradicative function for the vertical clearance between the anus and the cushion piece.
(Finger-Inserting Section 11)
The finger-inserting section 11 of this excrement disposal device 8 will now be described with reference to
Further, the finger-inserting sections 11 laterally displace the two base plates 9 by the movement of the fingertips A, adapted to move in conjunction with the opening and closing motion of the anus, in the horizontal direction, using a pin 15 serving as a pivot pin of the front and rear ends 13, 13 as a fulcrum to make the horizontal dimensions and the vertical dimensions of the mouth section G variable, thereby causing the mouth periphery 23 of the disposal bag 12 to open or close.
The finger-inserting section 11 will now be further described in detail. The finger-inserting section 11 is used in pairs (i.e., right and left finger-inserting sections) to be mounted on the right and left base plates 9. In an example as shown in
Each finger-inserting section 11 is provided with a finger-inserting hole 25 in the center. This finger-inserting hole 25 is formed in a longitudinally long rectangular shape by cutting the front and rear sections and the central section in a substantially I-shape and horizontal H-shape, respectively and laterally bending those sections to droop. A pair of right and left guide projections 26, 26 is formed by bending those sections to droop and function as a guide for a fingertip A.
The finger-inserting hole 25 of each finger-inserting section 11 is opposedly situated on the underside of the right and left areas D of the cutaway section C of each base plate 9. The right and left edges of the finger-inserting hole 25 are provided with right and left guide projections 26 to be drooped downwards. Inserted into the front and rear edges of the finger-inserting hole 25 to be drooped are the front and rear guide projections 16 as described above.
In this finger-inserting section 11, the fingertip A can be inserted into the finger-inserting hole 25 from the bottom up while being guided by the right and left guide projections 26 and the front and rear guide projections 16. The fingertip A can also be inserted into the right and left areas D of the cutaway section C, the corresponding area of the opening B and the right and left spaces H of the corresponding mouth section G, and can be directed to the mouth periphery 23 of the disposal bag 12.
In this manner, the finger-inserting section 11 can be moved in the horizontal direction by the inserted fingertips A to cause the right and left base plates 9, to which both finger-inserting sections 11 are fixedly secured, to symmetrically displace. With this, the lateral dimension and the vertical dimension of the mouth section G thereof are made variable to open or close the mouth periphery 23 of the disposal bag 12.
For example, when the fingertips A of the right and left finger-inserting sections 11 laterally move inside to come closer, the right and left base plates 9 and the front and rear wing plates 10 also come close to make the size of the opening B small, thereby making the size of the mouth section G small. To the contrary, in the case where the fingertips A of the right and left finer-inserting sections 11 laterally move outside to separate, the right and left base plates 9 and the front and rear wing plates 10 also separate to make the size of the opening B large, thereby making the size of the mouth section G large.
It is to be noted that the inner corner of one extended plate section 24 of the right and left finger-inserting sections 11 is designed to slightly warp downwards. With this design, when the inner corner of another corresponding extended plate section 24 moves closer, it slips into the inner corner of one non-corresponding extended plate section warped not to collide.
(Disposal Bag 12)
The disposal bag 12 of this excrement disposal device 8 will now be described with reference to
Namely, the disposal bag 12 is detachably and additionally provided, wherein an upper end section 28 of which the edge 27 is open is reversed to cover both base plates 9 and wing plates 10, and a bottom section 29 is adapted to receive an object excreted from the anus and house it.
Fingertips A can be inserted into the right and left spaces H of the mouth section G, respectively. The mouth periphery 23 of the disposal bag 12 is provided to control an enclosure which prevents the inserted fingertips A from projecting upwards to too great an extent. The shape of the mouth section G formed based on the opening B is controlled to make both the lateral dimensions and the vertical dimensions variable between the right and left fingertips A and the top sections 22 of the front and rear wing plates 10, wherein the mouth periphery 23 of the disposal bag 12 is formed in a substantially circular-ring shape and the like to match the shape of the opening and closing anus.
The disposal bag 12 is further described below in detail. The disposal bag 12 is formed in a pouched shape of about 350 mm high and about 180 mm wide and consists of the upper end section 28, the mouth periphery 23 and the bottom section 29. The bag 12 is always used in a substantially flat condition in which air is removed.
The upper end section 28 is provided with a hollow string passage 30 for lacing a string 31 around the edge 27. The disposal bag 12 is opened and closed by the operation of the string 31. The bag 12 is opened before and when used as the excrement disposal device 8 and is closed after use.
After the disposal bag 12 is vertically inserted into the mouth section G, the upper end section 28 is reversed to cover the base plates 9 and the wing plates 10.
The mouth periphery 23 of the disposal bag 12 not only includes a section vertically inserted into the mouth section G, but also an opening flat surface section adjacent to the vertically inserted section.
The right and left spaces H of the mouth section G are adapted to receive the two fingertips A respectively through the finger-inserting holes 25 of the finger-inserting sections 11, the right and left areas D of the cutaway sections C, the corresponding areas of the opening B, and the like. The vertical and horizontal size (shape) of the mouth section G formed based on the opening B is controlled by the inserted right and left fingertips A and the front and rear wing plates 10.
Since the disposal bag 12 of a larger diameter is inserted into the mouth section G of which the shape is controlled, and is reversed, the mouth periphery 23 of the disposal bag 12 is adapted to fit into the mouth section G and each corner section is additionally provided with a curvature to provide large overlapping wrinkles. Thus, the mouth periphery 23 of the disposal bag 12 is formed in a substantially circular-ring shape in many cases based on the curvature and the overlapping wrinkles on each corner.
Further, the size of the mouth periphery 23 of such a disposal bag 12 is made variable according to the opening and closing shape of the anus and the size change of the mouth section G.
More specifically, in the closed condition as shown in
In this case, the mouth periphery 23 of the disposal bag 12 becomes a minimum size in a substantially closed condition. Namely, the mouth periphery 23 becomes a groove-shape close to a vertical linear shape to correspond to the closed anus rather than a substantially circular-ring shape.
On the contrary, in the expanded condition as shown in
In this case, the mouth periphery 23 of the disposal bag 12 is formed in a substantially circular-ring shape to match the shape of the anus at that time, but this substantially circular-ring shape can be changed to various sizes depending on the opening and closing degree of the anus and the size change of the mouth section G.
The mouth periphery 23 of such a disposal bag 12 is affixed to the finger-inserting sections 11, the base plates 9 and the wing plates 10, respectively with, for example, a double-faced adhesive tape.
More specifically, the outer surface of the mouth periphery 23 of the disposal bag 12 is secured to one vertical surface of the right and left guide projections 26 of each finger-inserting section 11 near the center, the upper surface of the central section 14 of each base plate 9, and the edge of the top section 22 of each wing plate 10 (i.e., an area of the cushion piece described above) at, for example, six (6) locations, with the double-faced adhesive tape.
The mouth periphery 23 of the disposal bag 12 secured at these 6 locations is provided to surround and cover the fingertips A which are inserted into the right and left spaces H of the mouth section G to project and to control so that the fingertips A do not project further upward. Thus, the mouth periphery 23 of the disposal bag 12, secured in 6 locations, can stably be formed in a substantially circular-ring shape.
The bottom section 29 of the disposal bag 12 causes the object to enter through the mouth periphery 23 to be housed. As shown in
The waist body 32 is preferably made of a firm tape and the like which are harder than the resin film material etc. used in the disposal bag 12 and is affixed to the outer surface of the disposal bag 12 from the lower area of the mouth periphery 23 toward the bottom section 29. The waist body 32 functions to smoothly let an object, especially a soft object, flow from the mouth periphery 23 toward the bottom section 29.
(Operation and the Like)
The excrement disposal device 8 according to the present invention is constructed as described above and is used as described below.
(1) In use, the excrement disposal device 8 is first put on the palm of the left hand letting the string 31 face the front. The fingertip A of the first finger and the fingertip A of the second finger of the right hand are respectively inserted into the right and left spaces H of the mouth section G from below through the right and left finger-inserting sections 11 (This applies to a right-handed person. In the case of a left-hander, the right and left hands are reversed).
As shown in
In this case, the excrement disposal device 8 is provided so that the front and rear direction (i.e., the longitudinal direction) of the device 8 is directed to the right and left direction of the human body, while the right and left direction (i.e., the short direction) of the device 8 is directed to the front and rear direction of the human body.
(2) In this manner, the excrement disposal device 8 is applied to a subanal area from directly below. More specifically, as shown in
The excrement disposal device 8 is directed in this manner and the two fingertips A, A holding the excrement disposal device 8 are applied to the front and rear areas of the anus from directly below. The mouth section G is adapted to open and close depending on the subsequent approaching movement or receding movement of the two fingertips A.
(In the following description, the right and left direction of the excrement disposal device 8 including the fingertips A is the front and rear direction of the human body, and the front and rear direction of the device 8 including the fingertips A is the right and left direction of the human body.)
(3) As shown in
In other words, both fingertips A inserted into the right and left spaces H of the mouth section G from directly below can correctly grasp and identify the location of the anus from directly below through the mouth periphery 23 of the disposal bag 12. Both fingertips A grope for and confirm the location of the anus and are pushed against the subanal area after positioning through the mouth periphery 23 of the disposal bag 12.
In this manner, based on direct feel, that is, the tactile impression, of the fingertips A relative to the anus, the fingertips A can be correctly brought into line with the center of the mouth section G of the excrement disposal device 8, the center of the mouth periphery 23 of the disposal bag 12, and the center of the anus for proper positioning without causing any displacement and gap. Thus, the object is caused to enter the disposal bag 12 through the mouth periphery 23 and is collected as expected.
(4) In the excrement disposal device 8 applied onto the subanal area in this manner, the inserted two fingertips A, A are first caused to approach from the side to such a degree that they touch each other, as shown in
If an attempt to open the anus which becomes narrower is made with a free hand, the confirmation, identification and positioning of the anus position by the fingertips A, A of the hand which is involved in the operation of the excrement disposal device 8 described above can be facilitated further. The touch and approach of the fingertips A, A described above can also be highly facilitated. If the mouth periphery 23 of the disposal bag 12 of the excrement disposal device 8 and the fingertips A, A can be pushed into (the inside of) the anus thus opened, the positioning described above can be further ensured.
In this manner, if the positioning of the excrement disposal device 8 relative to the anus is correctly carried out, the sense of unity between the anus, which becomes narrower, and the fingertips A, A can be created.
(5) After being excreted, the object from the anus which selectively opens or closes flows to the bottom section 28 of the disposal bag 12 through the mouth periphery 23 of the disposal bag 12 of the excrement disposal device 8 and is housed.
Housing of the object by such an excrement disposal device 8 can be readily and surely carried out by leaving the opening and closing of the anus entirely to the two fingertips A pushed against the subanal area from directly below through the mouth periphery 23 of the disposal bag 12.
In the case of excretion, although the anus opens and closes, changing the width, depending on the diameter of the object, the excrement disposal device 8 can surely help facilitate proper housing of the object.
(6) In this excrement disposal device 8, the mouth section G formed based on the opening B is controlled to make the size thereof variable by the right and left (two) fingertips A pushed against the anus area and the front and rear wing plates 10. Thus, the mouth periphery 23 of the disposal bag 12 can be formed in a substantially circular-ring shape to match the shape of the anus.
When the anus opens or closes in conjunction with the excretion of the object, the two fingertips A, A playing an important role in the opening and closing motion of the anus open or close moving to symmetrically and laterally approach or separate. Based on this, the mouth section G is opened or closed, making the size variable depending on the motion of the anus, through each finger-inserting section 11, each base plate 9, each wing plate 10 and the like which symmetrically approach or separate in the longitudinal and lateral directions. In other words, the dimensions of the mouth section G are made variable by controlling the opening B formed between the two base plates 9 in the longitudinal and lateral directions between the inner side of the fingertips A and the top section 22 of the wing plates 10.
In this manner, the mouth periphery 23 of the disposal bag 12 is stably and surely formed in the expanded condition of a substantially circular-ring shape of varying size corresponding to the shape of the anus as shown in
The mouth periphery 23 of the disposal bag 12 moves depending on the diameter of the anus sequentially changing, that is, opening and closing of the anus in the width, without displacement and gap, and is opened or closed to overlap matching the diameter of the opening anus. As a result, the object flows into the disposal bag 12 through the mouth periphery 23 as expected and is collected.
(7) The opening and closing operation of the mouth periphery, 23 of such a disposal bag 12 can be more stably secured, guaranteed and facilitated by the overlapping of the right and left base plates 9, the existence of the bent section 18 formed on each base plate 9, the existence of the tongue pieces 19, fixation of the mouth periphery 23 of the disposal bag 12 with the double-faced adhesive tape and the like as described above. Further, positioning of the fingertips A, A, playing an important role in the opening and closing operation, in the center of the excrement disposal device 8 and in the center of the base plates 9 is also a factor contributing to the stable operation.
Also, opening and closing of the mouth periphery 23 of such a disposal bag 12 is carried out with curvature. Even from this aspect, a substantially circular-ring shape can be formed to match the shape of the anus which opens and closes.
Namely, the mouth section G is formed by the opening B of the base plates 9 and the wing plates 10, but these base plates 9 and wing plates 10 are adapted to move in the longitudinal direction or in the lateral direction to approach or separate while being bent. More specifically, the base plates 9 are provided to totally deform between the closed condition as shown in
With this arrangement, the mouth periphery 23 of the disposal bag 12 is provided to open and close keeping the same height on the same level. Thus, the mouth periphery 23 is adapted to surely match the anus which also opens and closes on the same plane surface and on the same height level without causing any displacement and gap. Even from this aspect, a substantially circular-ring shape can be formed to match the shape of the anus.
(8) By continuing to push the two fingertips A against the anus area from directly below through the mouth periphery 23 of the disposal bag 12, the edge of the top section 22 of the wing plates 10 through the finger-inserting sections 11 and the base plates 9 can also be continuously pushed against the anus area from directly below through the mouth periphery 23 of the disposal bag 12.
By such pushing from the vertical and lateral directions, it is possible to prevent a displacement and a gap from being caused between the mouth periphery 23 of the disposal bag 12 of a substantially circular-ring shape matching the shape of the anus and the anus.
Further, with this pushing, it is possible to readily cope with the vertical movement of the anus. Namely, in the case where the object is not soft, the anus often moves vertically. Even in that case, it is possible to surely prevent the displacement and a gap from being caused between the mouth periphery 23 of the disposal bag 12 and the anus by such pushing.
(9) When the excretion is over in this manner, the anus is closed, and the right and left fingertips A, A pushed against the anus also approach to such a degree that the finger cushions substantially touch each other and are closed, as shown in
By strongly closing the two fingertips A, A, the remaining object adhering to the anus area is grasped and housed in the disposal bag 12, and the mouth periphery 23 of the disposal bag 12 is also closed.
In other words, after the right and left fingertips A, A are respectively inserted into the finger-inserting holes 25 of the finger-inserting sections 11, the mouth periphery 23 of the disposal bag 12 is only provided between the two fingertips A, A. Namely, since nothing hard is interposed between them, the two fingertips A, A can be closed after closely approaching each other and as a result, the grasping function and the closing function as described above can be surely exhibited.
As shown in
Then, by pulling the string 31, the open edge 27 of the disposal bag 12 is closed. As shown in
(10) In this manner, the disposal bag 12 housing the object is removed from the excrement disposal device 8 (the double-faced adhesive tape is removed, if necessary). As shown in
The outer bag J is made of a non-porous material of which the odor-eliminating property is good. For example, a bag of aluminum foil is used.
As shown in
Referring to the example as shown in
(First Effect)
According to this excrement disposal device, it is possible to correctly and readily apply a mouth section to the subanal area for positioning.
In other words, in the excrement disposal device according to the present invention, by inserting the fingertips into the right and left spaces of the mouth section, it is possible to locate the anus with the fingertips through the disposal bag of the mouth periphery for confirmation and positioning before the fingertips are pushed against the anus. Namely, the fingertips can directly reach the anus through the mouth periphery of the disposal bag and, based on the mutual direct feel, i.e., the tactile impression, between the fingertips and the anus located by the fingertips, it is possible to readily realize the operation for correctly matching the center of the excrement disposal device, the center of the mouth section, and the center of the disposal bag of the mouth periphery with the center of the anus for positioning.
In this manner, the disadvantage as seen in the conventional excrement disposal device of this type whereby the location of the anus cannot be correctly grasped and specified, causing the excrement disposal device to be displaced from the anus, thereby producing a gap, can be surely prevented.
Thus, an accident whereby an object escapes from the mouth section and the disposal bag can be eliminated, and the object can be surely housed in the disposal bag. In this manner, the problems such as adhesion (adherence) of the object to the body, soil and odor can be surely eliminated and solved to greatly improve the cleanliness.
(Second Effect)
According to this excrement disposal device, the operation is stable and the mouth section is adapted to open and close in accordance with the opening and closing motion of the anus.
Namely, in the excrement disposal device according to the present invention, the mouth section formed by the opening of the base plates is controlled to make the size variable by the fingertips pushed against the anus area and the wing plates. With this, the mouth periphery of the disposal bag can be formed in a substantially circular-ring shape to perfectly match the shape of the anus. When the anus is opened or closed in excretion, the fingertips playing an important role in the opening and closing motion of the anus move to allow the mouth section to open or close according to the anus. Thus, the mouth periphery of the disposal bag can be stably and surely formed in the substantially circular-ring shape to match the shape of the opening and closing anus.
Further, such a stable operation can be guaranteed and accelerated by factors such as the overlapping of the base plates, the curvature of the base plates, tongue pieces of the base plates, tying up of the mouth periphery of the disposal bag, and positioning of the fingertips in the center.
Thus, the situation as seen in the conventional excrement disposal device of this type described above, in which the mouth section does not move according to the opening and closing motion of the anus, is not caused and as a result, production of a displacement or gap can be surely prevented.
Even from this aspect, an accident whereby the object escapes from the mouth section and the disposal bag can be eliminated, and the object can be surely housed in the disposal bag. Accordingly, the problems such as adherence of the object to the body or fingertips, soiling and fecal odor can also be eliminated and solved to greatly improve the cleanliness, and the smell can be cut off as well. It is to be noted that the anus area can be made clean to such a degree that wiping out with paper or washing with water is not necessary and outflow of the odor can be surely prevented.
As described above, the present invention has a great effect in that all the problems of the conventional excrement disposal device of this kind can be solved.
